Objective To observe the therapeutic response of liver tumors by arterial embolization hyperthermia with Nano Superparamagnetic Iodized Oil(NSIO)using rabbit VX2 liver tumor model.Methods A total 24 rabbits containing experimental hepatic tumors were randomly assigned to one of four groups as follows:NSIO embolization hyperthermia group(group A),Lipidol embolization group(group B),NSIO embolization group(group C),and contronl group(group D),each groups contain 6 VX2 rabbits.Fourteen days after implantation of the experimental hepatic tumor,VX2 rabbits were treated.In group A group B and group C,the rabbits hepatic proper artery were selectively catheterized by 3 Fr microcatheters via right femoral artery under fluoroscopic guidance.10% NSIO 0.5 ml(group A and group C)or Lipidol 0.5 ml(group B)infused into proper hepatic artery.Three days after embolization,the rabbits in group A and group B were exposed to gap-type alternating magnetic field for 30 minutes,while rabbits in group C and group D have not been exposed to alternating magnetic field.The liver tumor size were measured by CT scanning before and 14 days after treatment then the animals were sacrificed,the liver,lung,heart spleen and kidney were harvested for histopathology examination,the liver tumor size were detected directly. Results All subjects experienced uneventful 14 days surivials,on the biochemical examination,there were no changes about the function of liver and renal in each group 14 days after treatment compare to pre- treatment.Fourteen days after treatment,the tumor size decreased by 8.09% in group A,but increased by 9.72% and 13.00%(P＜0.05)in group B and group C respectively,in group D,the tumor size increased by 57.50%(P＜0.01).In histopathology examination,the tumor necrosis in three treatment groups were manifest,particular in group A.Conclusion Arterial embolization hyperthermia with NSIO has obvious therapeutic response to experimental hepatic tumors,it encourages further development of this technology for the treatment of liver cancer in humans.

Objective To compare the therapeutic effect of the combination of ~(99m)Tc-methnetium methylene diphosphunate and colloidal chromic,phosphate ~(32)p with the monotherapies in rats with adjuvant arthritis(AA).Methods In this study,50 Sprague-Dawley rats were randomly divided into five groups with 10 rats in each:normal control group(arthritis induced and treated with the same volume of normal saline via the same administration route),AA control group(arthritis induced with adjuvant and treated with normal sa- line),~(32)p colloid group(arthritis induced with adjuvant and treated with single intra-articular injection of col- luidal chromic phosphate ~(32)p 0.74 MBq and intra-peritoneal injection of normal saline every other clay),~(99m)Tc- MDP group(arthritis induced with adjuvant and treated with intra-peritoneal injection of ~(99m)Tc-MDP 2.5?10~(-3)?g/kg every other day and single intra-articular injection of normal saline),combination group(arthritis in- duced with adjuvant and treated with the combination of the two drugs).The diameter of the left hind ankle, serum levels of turnout necrosis factor(TNF)and interleukin-1?(IL-1?),and the pathological changes of an- kle joints were tested at different time points.Results The diameter of the left hind ankle at week 4 was smaller in the combination group than that of the ~(32)p colloid treatment alone group [(7.11?0.34)mm vs(7.57?0.29)mm,P

Inoculant the examine-needed germ on a flat panel of synthetic medium, and placed paper slices, which had being saturated by different kinds of sugar, on the medium to carry out the experiment of microorganic auxanography. Its result was compared with that of the traditional method, the sugar-grain method. The comparison showed that the former was better than the latter for its more definite result and more convenient operation.

Objective To explore the relationship between fluconazole resistance and expression of multidrug resistant protein genes,including CDR1,CDR2,MDRI.Methods The total RNA was extracted from fluconazole-resistant and -susceptible Candida albicans isolates,and cDNA was synthesized.The expression of CDR1,CDR2 and MDRl genes was then detected by quantitative real-time PCR.The?CT (threshold cycle) value was obtained by subtracting the CT value of 18S rRNA from that of the targeted gene.Results The?CT value of CDR2 was significantly lower in fluconazole-resistant isolates than in fluconazole- susceptible isolates (7.52?2.53 vs.9.28?3.15,t=2.367,P

Objective To study whether carbon dioxide used to establish pneumoperitoneum has an influence on port-site and intraperitoneal implantation and metastasis of tumor cells. Methods R 15 hepatic cancer cells were injected into 30 Wistar rats’ peritoneal cavities 1 hour before operation, then the 30 Wistar rats were randomly divided into 3 groups: gasless group, helium group and carbon dioxide group. The suspension was exposed to the gas environment for 2 hours, all animals were killed after 28 days and the port-site and intraperitoneal implantation and metastasis of tumor cells were examined.Results On port-site, intestinal serous coat, mesentery, greater omentum and diaphragm, the weights of tumor cells, in carbon dioxide group were (326.7?230.3) mg, (626.2?215.9) mg, (476.2?204.8) mg,(2 536.5?906.7) mg and (384.5?149.9) mg respectively; in helium group were (235.6?107.3) mg, (414.2?148.4) mg, (261.8?92.6) mg, (1 633.4?247.3) mg and(220.0?57.9) mg; in gasless group were (145.0?42.4) mg, (221.5?108.2) mg, (212.5?109.6) mg, (797.5?335.9) mg and 113.0 mg.The weights of carbon dioxide group showed a significant increase, compared with helium group and gasless group (P 0.05). Conclusion The insufflation of carbon dioxide promotes intraperitoneal tumor implantation and growth compared with helium and gaslessness in a rat model.

Thirty four residents of general practice and 11 students of junior college to undergraduate program were evaluated with the mini-clinical evaluation exercise (mini-CEX) when they were rotated to community clinics or the ward of general practice in Zhongshan Hospital from September 2009 to February 2010. The reliability and validity of mini-CEX for rotation examination in general practice training was assessed. Forty five trainees and 9 clinical faculty members completed 81 mini-CEX evaluations. The Cronbach's alpha coefficient was 0. 932. Criterion-related validity for mini-CEX overall competence with the end examination of rotation was O.53 ( P ＜ 0.001 ). The results indicate that mini-CEX may be an appropriate evaluation tool for rotation examination in general practice training.
